High blood pressure is a common complication of chronic renal failure, with about 70 to 80 percent of patients experiencing elevated blood pressure. Controlling blood pressure is also an important aspect of the treatment of chronic renal failure. Generally, it is best for such patients to keep their blood pressure below 130/80 mmHg, with systolic pressure below 130 mmHg and diastolic pressure below 80 mmHg. If a patient’s 24-hour urinary protein quantification exceeds 1 gram, the blood pressure control requirements are even more stringent, ideally below 125/75 mmHg. Adequately controlling blood pressure also helps to slow the progression of chronic renal failure.
